Abstract: 895,553. Flexible hoses. UNION CARBIDE CORPORATION. Feb. 23, 1961 [Feb. 24, 1960], No. 6643/61. Class 99(2). A hose for transporting low-temperature liquids comprises a flexible, corrugated metallic conduit 10 for such liquid, a larger flexible, corrugated metallic jacket 11 concentrically spaced around the conduit 10 so as to form an evacuable, annular, insulation space 12 therebetween and flexible, composite heat-insulating and radiation-impervious material 13 substantially filling the space 12. The material 13 comprises a multiplicity of radiation-impervious barriers 16 and low heat-conductive fibrous layers 15 coextensive with such barriers and disposed in contiguous adjacency between and in alternating sequence with the barriers for separating and maintaining the barriers spaced from each other and for reducing the heat transmission by gaseous conduction without substantially increasing the heat transmission by solid conduction, the individual fibres of such low conductive layers being orientated substantially parallel to the radiation-impervious barriers and substantially perpendicular to the direction of heat inleak across the insulation space, such space being under an absolute pressure of below about 30 microns of mercury. The stainless steel annularly or helically corrugated conduits 10, 11 may each be provided with braided wire coverings 14, and the barriers 16 may be of metal, such as tin, silver, gold, copper or cadmium, metal oxide or metal coated material such as aluminium-coated plastic film, but is preferably of aluminium foil. The heatinsulating layers may be in the form of precompressed sheets of unbonded glass fibre or wool. There may be means for the removal of gases which accumulate in the space 12. In making the hose, the radiation-impervious strips are helically wrapped without bonding so that the convolutions thereof overlap; the heatinsulating material may be wrapped helically or convolutely. Alternatively the strips and material are overlaid and helically wound simultaneously, the heat-insulating material having a greater width than that of the strip.

Title: Method of heating and plant for annealing metallic material or of smelting ores
IPC: C21B13/00
Filed: 1935-03-05
Abstract: 458,168. Metal-heating and metallurgical furnaces. DODERER, W., 12, Stammgasse, Vienna. March 5, 1935, No. 6920. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 7, 1935]. [Class 51 (ii)] In a tunnel-type furnace for the treatment of materials in a controlled gaseous atmosphere, e.g. for use in annealing metals or reducing ores, the hot gas is supplied to the furnace by one or other of a pair of hot blast stoves and passes in counter-current to the charge, the gases leaving the furnace at the charging end being divided, a portion being recirculated with the addition of fresh gas through the active stove, while the remainder is supplied for combustion in the stove which is being heated up.

Title: Improvements in or relating to electromagnetic apparatus for measuring torque
IPC: G01L3/14
Filed: 1945-03-20
Abstract: 596,983. Dynamometers. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 20, 1945, No. 7000. Convention date, Nov. 19, 1942. [Class 106 (ii)] Apparatus for continuously measuring torque comprises a stationary member, subject to the torque output and comprising relatively angularly displaceable sections, at least one electromagnetic member and a co-operating magnetic member mounted respectively on the two relatively displaceable sections of the stationary member, means for producing a voltage varying with changes in relation of the two magnetic members and means for measuring the voltage to indicate the torque. To measure the torque of an aero-engine, the latter is mounted in the usual manner on a ring 1 connected to a ring 4 by means of a framework 3. The ring 4 is not, however, mounted directly upon a firewall 2, but is carried by spacing members 6 secured to a further ring 5 which is itself secured to the firewall. In this manner, the engine torque produces a counter torque which results in a relative angular displacement of the rings 4 and 5. Such displacement is measured by means of a pair of diametrically opposed magnetic strain gauges, each of which comprises a pair of E-shaped core members 18, 19, each having a coil wound about its central leg, secured to the ring 4 and an armature 25 carried by the ring 5 and disposed between the confronting core members. A relative angular displacement of the rings 4 and 5 thus varies the magnetic flux path associated with each coil and increases the impedance of one of each pair of coils and decreases the impedance of the other coil of each pair. The coils are connected to form a bridge, Fig. 8, the output of which is fed through a bridge rectifier 41 to a coil 40 of a cross-coil indicating instrument. A bridge rectifier 42 is also connected across the source of alternating potential of the bridge and has its positive and negative terminals connected to the other coil 39 of the indicating instrument which therefore indicates changes in voltage across the bridge circuit independently of fluctuations in the alternating potential. The instrument may be calibrated to read torque directly and may be set to zero by means of a small biassing battery and rheostat. In an alternative circuit, Fig. 5, the two pairs of coils respectively form two arms of a bridge, the other arms being formed by a potentiometer 28 which may be used for zero adjustments. The output of the bridge is fed to an indicating instrument 31 via a bridge rectifier. If it is desired to measure the power output of the prime mover, a tachometer generator 32 is provided to produce a voltage proportional to the speed of operation of the prime mover. This voltage is multiplied by that due to the bridge unbalance in an indicating instrument 43 which may be calibrated to read horsepower directly. The magnetic strain gauges may alternatively be mounted to measure the torsional deflections of a sun gear in the planetary gear reduction unit of the aircraft engine itself.

Abstract: 715,093. Reciprocating motors. I.T.E.M. SOC. R.L. March 18, 1952 [March 27, 1951], No. 7002/52. Class 35 [Also in Group XXIII] A machine for treating substantially plane surfaces, e.g. floors, comprises a shallow, upwardly dished housing containing an electro-magnetic motor comprising an electro-magnet and an armature reciprical rectilinearly with respect to one another and a work plate guidedly mounted with regard to the housing and reciprocable in its own plane, the plate substantially closing the underside of the housing and being connected to the motor for reciprocation, thereby in synchronism with an alternating, pulsating or non-continuous undirectional current applied to the motor. The electromagnet motor comprises an iron core 1, preferably laminated, with pole pieces 23 and exciting coils 4, 5; the pole pieces have teeth 2<SP>1</SP>, 3<SP>1</SP> corresponding to teeth 6<SP>1</SP> on the ferro-magnetic armature 6. The core 1 is mounted, preferably resiliently, within a flat housing 16; a supplementary mass may be secured to the core to increase its mass with respect to the armature. The ends of the armature 6 are secured to U-shaped members 11, 12 which straddle the end limbs of the core; springs 13, 14 are interposed between the outer limbs of the members 11, 12 and adjusting screws 17, 18 mounted in the housing 16. The ends of the limbs of members 11, 12 are secured to a plate 15 which substantially closes the lower open end of the housing 16. Ball bearings 7, 8 are fitted between the members 11, 12 and the end limbs of th core; ball bearings 9, 10 are fitted between the plate 15 and the side limbs of the core. The ball bearings may be replaced by flat springs which supplement or replace the springs 13, 14. A stirrup 19 pivoted about an axis 19<SP>1</SP> to the opposite longitudinal sides of the housing 16 carries a handle; the stirrup may be resiliently connected to the housing 16 and/or the handle may be furnished with sponge-rubber or like vibration-absorbing hand grips to prevent transmission of vibrations from the housing to the hand of the user. One or more low-voltage electric lamps 21 are arranged in the front end of the housing 16 to illuminate the floor in front of the machine; the lamps are energized by a coil wound about a limb of the core 1. The plate 15 is so formed as to enable tools such as sanding, grinding, cleaning, scraping or polishing pads to be attached thereto; the lower surface of the plate 15 may be contoured to act as such a tool itself.

[Class 103 (v).] Buffing and draw gear for railway vehicles comprises the combination of outside buffers with central buffing and draw gear having a plurality of springs 16, 17, 18 operative in series on buff to give movement consonant with that of the outside buffers, and in parallel on draw. The coupler shank 1 shown equipped with an M.C.B. coupler 12 is pivoted at 14 to a draw-rod 15 supporting the springs which on draw are compressed equally by nuts 33, 34, 35 on the draw-rod 15 acting on plates 20, 22, 24, corresponding plates 19, 21, 23 abutting fixed projections 29, 30, 31 integral with draw sills 25, 26 which are carried by reinforcing castings 27, 28 riveted to the centre sills 3, 4 and extending between the end sill 2 and bogie-carrying transom 5. In buffing the thrust is transmitted gradually through each spring to the plate 24 and stops 32. The stem 7 of each of the outside buffers passes through a buffer case 8 and the end sill 2 to operate under normal impacts an indiarubber spring 9 while under more intensive impacts the head 6 engages a sleeve 10 acting on a high capacity spring 11. In a modification the outside buffers are single-acting, the auxiliary draw sills are riveted directly to the centre sills, and the load on buff is distributed by the rods fixed to the end sill 2, some of the rods being adjustably secured to the transom and some extending to the other end sill of the vehicle. Helical steel springs or friction gear may replace or supplement the indiarubber springs and the central gear may be embraced by a yoke. During the conversion of the stock to automatic couplers the coupler shank 1 may be replaced by a hook mounted on the pin 14 or by a shank, hook, and arm carrying an automatic coupler.

Abstract: 867,496. Waveguide mode suppressors. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1960 [March 3, 1959], No. 7317/59. Class 40(8) A waveguide mode-filter for suppressing undesired high-order modes comprises a thin layer of magnetically lossy material supported in a region of the waveguide where the magnetic field component of a desired low-order mode is negligible and that of an undesired higher-order mode is close to its maximum intensity. As shown, a lossy magnetic cylinder 2 of radius 0À628R is supported by foamed polystyrene members 3, 4 within a circular waveguide 1 of radius R intended for propagation of the H 01  mode. The longitudinal field of the H 02  mode approaches its maximum intensity in the region of the magnetic cylinder and fields due to the H 03  and other modes of higher order have non- zero intensities in the same region. The cylinder 2 may be a solid piece of nickel-zinc ferrite or may be formed by winding magnetic recording tape around the inner support 4. Alternatively, it may be formed by painting the surface of either of the supports 3. 4 with a slurry containing powdered ferrite. The layer may be permanently magnetized or biased by an external field.
